The most centrally located feature in a point, line, or polygon input
Density analysis takes known quantities of some phenomenon and spreads them across the landscape based on the quantity that is measured at each location and the spatial relationship of the locations of the measured quantities.
Conceptually, a smoothly curved surface is fitted over each point. The surface value is highest at the location of the point and diminishes with increasing distance from the point, reaching zero at the Search radius distance from the point.
Kernel density estimation is shown without a barrier (1) and with a barrier on both sides of the roads (2).
Could the distribution of Walmart stores in MA have been the result of a CSR process?
ArcGIS’ average nearest neighbor (ANN) tool computes the 1st nearest neighbor mean distance for all points. If ANN_ratio = 1, we have a random process. If ANN_ratio > 1, it is dispersed, and if ANN_ratio < 1 it is clustered.
MC - Administrative area of the Principality of Monaco. This term is used frequently in statistics to denote repeated simulated outcomes.
Now imagine that we can take into account other factors (population density, median income) when generating random realizations of Walmart siting.
\(p\)-value is below 0.05, we can reject null hypothesis. Population density affects the placement of Walmart stores.
